Where do you pay tax?
Residency-based taxation
Portugal taxes its tax residents on worldwide income. You become a tax resident once you spend more than 183 days in Portugal in a given year, or once your centre of vital interests shifts there.
Days of presence include partial days. Border-runs to game the clock are routinely challenged by tax authorities.
Home country obligations
United States taxes its citizens on worldwide income regardless of residence. You will continue to file annually with your home tax authority even when you owe nothing.
Treaty
The United States–Portugal Double Taxation Agreement
The DTA allocates taxing rights and provides a foreign tax credit so the same income is not taxed twice. Article 15 typically governs employment income — taxable where the work is physically performed, with credit relief in the country of residence.
US citizens — special case
Worldwide taxation, for life
The United States taxes its citizens on worldwide income regardless of residence. As a US citizen in Portugal, you file taxes in both the US (Form 1040) and Portugal. The DTA and the Foreign Tax Credit prevent paying the same tax twice — but the filing obligation remains every year.
